Carbon dioxide levels have been rising since the burning of fossil fuels began during the Industrial Revolution. This greenhouse gas is raising temperatures around the planet, altering the chemistry of our oceans, and destabilizing climate. New technologies are emerging to capture carbon and invent sustainable solutions to prevent worst-case scenarios. This panel will look at how scientists track carbon dioxide, the development of new tools designed to ‘bend the curve’ towards a more sustainable future, and the curiosity and collective action needed to get us there.
